Specification of Letters Patent: 14 192g) Application filed April 29, 1920. S-erialiNo. 377,530.

To all whom it may concern: v 7 Be it known that I, JOHN L. DAY, a citizen of the United States of America, residing at ltLemphis, in the county of Shelby and.

State of Tennessee, have invented certain new and useful Improvements in Fuel- Tanks, of which the following isa specification. I

My present invention relates generally to fuel tanks, and more particularly to tank wagons which are commonly provided with small upper filling spouts communicating with their one or more compartments and having valved caps from which there is commonly a good bit of leakage due to over filling, in the placement and removal or" filling spouts, and also due to the jolting and jarring of the vehicle over rough roadways, my object being the provision of simple,

comparatively inexpensive additions to the In the accompanying drawings I have shown a motor tank truck generally at 10, the tank of which appears at 11 and may be divided into several compartments as is commonly the case, eachcompartment having a small upper filling spout 12 which is ordinarily provided with a cap having a safety valve forming a vent and from which under ordinary circumstances there is considerable waste of gasolene or other fuel oil from the tank due to the jolting and jarring over rough roads and careless placing and removal of filling tubes. This waste ordinarily runs down the sides of thetank and drips from its lower portion, and to prevent this waste I provide the tank with an upright cylinder 13 rising therefrom in spaced relation around and above each filling spout 12, each cylinder forming a catch basin therein around the filling spout and having an upper cap '14 provided with a safety valve 15, removal of'the cap 14 permitting of ready access to the filling shout 12. l I

The lower side portions of each of the cyllnders 13 are connected by depending pipes 16 to a lower waste storage tank 17, the latter of which mayhave an outlet valve 18 of either the ordinaryform or provided wlth a lock 19 so that its manipulation is preventedexcept at the filling station if'it is so desired. These several catch basin outlet pipes 16 may be connected to one another so as to provide for a single connection at each side of the'waste tank 17 as in Fig. 1, or, in case different fluids are utilized in the several tank compartments, a waste storage tank l7 as in Fig. 3 may be provided with a similar number of compartments 17 b and the catch basin outlet pipes 16Fmay I lead separately to these compartments as shown in order to avoid comming'ling of the different fluids. v

In either event it is obvious my invention provides very simple attachments which" 7 will soon pay for themselves in the salvage of present waste, and will avoid difliculties between drivers and filling station superintendents as to the amount of waste under present circumstances and will bring about more equitable'relation between concerned.

all parties It is furthermore obvious that while I have shown my invention as applied to tank wagons, it is obvious it is equally applicable j to other portableliquidconveyances, such as tank railway cars and the like and that in either use it will be effective and etficient for the intended purposes.

I may vary the described construction to i the extent of providing the top of the tank 11 with openings inside the cylinders 13 and at opposite sides of the filling spouts 12." These openings are normally closed, by plugs 20 and by removing the plugs 20 and inserting plugs of any suitable character within the adjacent ends of the'pipes16,

when filling the tank 11, any liquid spilling within the cylinders will be allowed to drain into the tank instead otrunning downwardly into the waste tank. I

I claim V 1. A portable fiuidtank-having anupper I v filling spout a cylinder around the filling spout in spaced relation and extending thereab'ove, a valved cap for normally closing the cylinder, a Waste storage tank, and a pipe connection leading from the lower portion of the cylinder to the said Waste tank as described' Y 2. A portable liquid tank having an upper fillinglspout, means forming a catch basin around the filling spout and extending 10 basin has a pipe connection, having a valved I outlet as described.
